Beit known that 1, MARK E. HUNTER, a citi-' zen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Clamps for Holding Plate-Glass, of which improvement the following is a specification.

This invention relates to certain new and useful improvements in glass-clamps, and more particular to that class of clamps employed to support and holdplate-glass in windows, show-cases, and thelike,

The object of my invention is to provide a clamp which will allow a window-light to settle or adjust itself, at the same time giving sufficient rigidity to the glass to hold and support it in position.

Another object of my invention is to construct a clamp which will be simple in construction, comparatively inexpensive to'manufacture, and highlyefficient in operation.

Heretofore considerable trouble has been experienced in the cracking and breaking of plate-glass on account oft he settling or slight sagging of the same, the break in the glass often being due to the holeswhich have been drilled or filed in the glass to permit the clamping ofthe glass together, and it is one of the main and essential features of my clamp that the drilling of holes in the glass is entirely dispensed with.

With the above and other objects in view reference will be had to the accompanying drawings, in which like letters of reference indicate like parts throughout the several views of the drawings, in which- 7 Figure 1 is a perspective view of my improved clamp. Fig. 2 is a top plan View.

Fig. 3 is a rear view of the body portion with being formed at an angle suitable to the angle at which the glass is to be held, and in the drawings I have shown the clamp formed nearly at a right angle. This metallic strip 1 has its ends enlarged, as indicated at 2, and

the rear faces of the sides-3 and 4 cut away, as shown at 5. The vertex formed by the sides 3 and 4 is cut away, as shown at 6, said cut-away'portion extending the width of the clamp, and in this cut-away portion is socured the shank 7, said shankbeing formed integral with a metallic strip 8, and upon the outer end of said strip 'is secured the screwthreaded stem 9, and upon this stem is mounted the adjusting member 10, which clamps the glass 11 to the clamp proper, as indicated by -the referencemumeral 1. .The adjusting member 10 has its twoextending ends 12 and 14 formed at an angle corresponding to the clamp proper, 1, and to secure and adjust the member 10 I provide a nut or top'15 upon the screw-threaded stem 9. Y

Mounted upon the rear faces 16 and 17 of the sides 3 and 4, respectively, and adj ustably seated in the cut-away portions 5 are the clips 18, said clips being slidably mounted upon the rear faces 16 and 17 by means of a lug 19, formed integral with the rear faces 16 and 17. The clips 18 have slots 20, whichiengage over the lugs 19and hold the clips from dropping from the cut-away portions 5. Theseclips are substantially the shape illustrated in Fig. 4 of the drawings, said clips having formed near one end thereof a lug or stud 21, which engages in a depression or recess 21 formed in the inner faces of the glass to be clamped. The clips 18 are supported and held in position by spring-shields 22, said shields being secured at their outer ends by any suitable means upon the rear faces 16 and 17, while theirother ends project from the rear faces,

: as shown at 23, thus forming a spring-surface upon which the glass bears. These shields 22 are 'cut away, as indicated at 24, to allow the lug 21 to project into the glass.

From the above description it will be seen that I have constructed my'improved clamp in such manner as to allow the window to adjust itself to the conditions caused by windy by said shank and supporting the auxiliary clamp, adjustable clips carried upon the rear faces of the body portion lugs formed integral'with said clips, spring-shields protecting and supporting said clips, substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing Witnesses.

MARK E. HUNTER.
